1-Point Recognition

Only the X and Y elements are corrected. The θ element (expansion,

etc.) is not corrected.

Fig. 3B43

2-Point Recognition

Specify fiducial mark positions so that one fiducial mark is kept as

diagonally away from the other as possible.

Fig. 3B44

Avoid fiducial mark positions aligned horizontally or vertically

with each other as shown below.

Fig. 3B45

3-Point Recognition

Specify fiducial mark positions so that the triangle area formed by con-

necting the three points (three fiducial marks) becomes as large as

possible.

Fig. 3B46

When any two of the three fiducial marks are designated to

be positioned as close as possible to each other, the results

of the correction will be almost the same as "2-Point Recog-

nition".

P.E.C. recognition mode image

When "Enable" is selected, select one of the following options as an

image recognition mode.

Disable : The image recognition function is not used.

Enable : The image recognition function (2 point) is used.

U-N : The P.E.C. recognition is performed, regarding

a unit P.C.B. as one unit on the multi-unit P.C.B.

When the global recognition function is used together with the

image recognition function, both recognizing actions take

place but the placement coordinates are corrected according

to the result of the image recognition.

(A02_02) P.E.C. recognition mode global

When "1 Point", "2 Point", "3 Point" or "4 Point" is selected for the

global P.E.C. recognition function, the coordinates and code of each

fiducial mark must be entered in the corresponding text boxes.

Fiducial mark #1 X location [mm] and Y location [mm]

Set the coordinates of the first fiducial mark in the text boxes.

Unit: mm

Fiducial mark #1 Mark #

Set the mark code of the first fiducial mark in the text box.

Fiducial mark #2 X location [mm] and Y location [mm]

Set the coordinates of the second fiducial mark in the text boxes.

Unit: mm

Fiducial mark #2 Mark #

Set the mark code of the second fiducial mark in the text box.

Fiducial mark #3 X location [mm] and Y location [mm]

Set the coordinates of the third fiducial mark in the text boxes.

Unit: mm
